html-effectiveness-review
Sub-skill — code review and understanding. Use when the user requests PR review, PR writeup (author side), or needs to understand the request path/call stack of an unfamiliar code module. Includes three paradigms: PR review (diff.html), PR writeup (pr.html), and module diagram. Load when the parent skill routes a request of the "review/PR/review this/how does this code work" type.
